Introduction to SDS/MTH 290

What makes a study an "Experiment"?

  • Can you assign experimental material to conditions?
  • You've created those conditions
  • If the material alredy comes in different “varieties”, then it's an observational study
    • People with different psychiatric illnesses
    • Different species of plants
  • Sometimes one “study” will have both experimental and observational variables

Our First Experiment

Our First Experiment

In your groups:

  • Take turns describing what you saw/did.
  • Your objective, as a group, is to describe the FULL experimental design.

Discussion questions:

  • What were all of the possibilities? How do you think that was determined?
  • Which conditions were distributed across people, and which within people?
  • What do you think are the possible research questions answered by this study?
